I am trying to make xen-virtualization
system
My machine is
CPU : Intel Xeon E5520 * 2
RAM : DDR3 1333 2GB * 6
HDD : 500GB SATA * 4 (RAID 10)
CentOS5.3 Kernel –
2.6.27.29-0.1.1 (original was 2.6.18-128 and I upgraded)
Xen – 3.4.2 (http://www.gitco.de/repo/GITCO-XEN3.4.2_x86_64.repo)
When I boot my computer, it shows some
messages like below;
Starting xend: Nothing to flush
FATAL : Module netloop not found
FATAL : Module netlbk not found,
FATAL : Module blkbk not found,
FATAL : Module blktap not found,
And when I reboot It starts to hang.
As I surveyed, from Xen 3.3 and later, we
should install above modules in Xen-kernel, not separate modules.
So I set those modules install in
xen-kernel.
(I mean, when we set menuconfig (make
menuconfig), it should be [*], not [M])
However, when I look through the
/etc/init.d/xend source, they have “modprobe” sentence.
So I changed all those modules as ‘<M>’ in menuconfig.
After this, netloop and netbk was installed,
however, blkbk and blktap was not installed.
So, I installed netloop and net bk as
Module, and blkbk and blktap in xen-kernel.
The, I boot my computer, it shows some
messages like below;
Starting xend: Nothing to flush
FATAL : Module blkbk not found,
FATAL : Module blktap not found,
And when I reboot, it starts to hang again!
After that, I commented out “modprobe blkbk” and “modprobe blktap” in /etc/init.d/xend file.,
then it doesn’t show those messages,
However, it hangs again.
When I boot my machine without xend, then
it does not show hang.
And I did googling and I found that other
people have same problem like me, and it is caused by blktap.
And some people give some solutions and
patch for blktap, however, those kernel version or xen version is different
from mine, So I could not apply them to my computer.
Follows are links that I referenced

Is there any solution or patch files for
this problem?
